Section 9 Power-Down Modes and Software Reset
9.7
9.7.1
To enter hardware standby mode, set the CA pin low. In hardware standby mode, all modules
except for any modules that run with RTC clock are halted as well as in standby mode entered by
sleep instruction.
Differences between hardware standby mode and standby mode are as follows.
1. Interrupts and manual reset are not accepted in hardware standby mode.
2. The TMU does not run in hardware standby mode.
Operation when the CA pin goes low depends on the CPG status.
1. In standby mode
2. During WDT runs when clearing standby mode with an interrupt
3. In sleep mode
Note that CA pin must keep low during hardware standby mode.
9.7.2
Hardware standby mode can be cleared only by power-on reset.
The clock starts oscillation by setting CA pin high while RESETP pin is low. At this time, keep
the RESETP pin low until the clock oscillation settles. Then, the CPU starts power-on reset
processing after setting the RESETP pin high.
The operation is not guaranteed when an interrupt or manual reset is occurred.

The chip enters hardware standby mode, clock remains halted.
Interrupts and manual reset are not accepted and the TMU halts.
The chip enters hardware standby mode after the CPU resumes operation once standby mode is
cleared.
The chip enters hardware standby mode after the CPU resumes operation once sleep mode is
cleared.
